Map as of 3:00 p.m. HST, May 28, 2018. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.

This thermal map shows the fissure system and lava flows as of 1:15 pm on Monday, May 28. The flow from Fissure 8 that reached Pohoiki Rd. this morning stalled, though activity restarted at Fissure 8 in the afternoon shortly after this map was made. The channelized flows that had reached the ocean were inactive today - a small amount of residual lava was draining from the abandoned eastern channel into the ocean, creating a weak ocean entry plume. Fissure 22 restarted today with lava starting to reoccupy the drained channel. The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.

This is a Civil Defense Message for 6 p.m., Monday, May 28, 2018.

Hawaiian Volcano Observatory reports that a fast-moving pahoehoe flow from Fissure 8 is advancing on Nohea and Kupono Streets north of Leilani Street. There are reports of lava fountains on Moku Street.  Anyone in the area, from Pomaikai east, needs to leave now.

Due to the volcanic activity, the following policies are in effect:

  • Residents close to the active eruption need to leave the area to avoid being isolated by the flow.
  • Authorities are going door to door on the affected streets.
  • Stay alert for warnings from Civil Defense Officials
  • The Pahoa Community Center, Keaau Community Center, and Sure Foundation Church are open.  The shelters are pet friendly.

The Napet-friendlyer Service reports light easterly winds are expected to push volcanic gases westward. This includes increased ash and sulfur dioxide downwind of the Kilauea summit and fissures on East Rift Zone. Leilani Estates has high levels of vog and sulfur dioxide (SO2).

Due to volcanic activity and weather changes, the following guidance is given:

  • Take action to limit exposure to ash and volcanic gases by staying indoors or leaving the area.
  • The Department of Health recommends limiting outside activities and stay indoors if you have breathing issues. If possible, close the windows and use your air conditioner.
  • N-95 masks that were distributed are for ash particulate and do NOT protect from gasses or vapors, including SO2.

Regarding upcoming meetings:

  • An eruption community information meeting will be held at the Pahoa High cafeteria on Tuesday, May 29 at 5 p.m.
  • A second meeting to discuss increasing vog and ash exposure in the Ka‘u District will be held at the Ka‘u High School multi-purpose room on Wednesday, May 30 at 5:30 p.m.

HELCO reports that power interruptions are likely in the lower East Rift Zone. Due to the work in the area and the volcanic activity, the following is provided for your information:

  • HELCO will be rerouting power to the Leilani Estates and the lower Puna areas starting at 3 p.m.
  • Be aware of downed power lines. Always assume power lines are active and exercise extreme caution.

Due to the lava entry at the ocean, the following policies are in effect:

  • Access to the area is prohibited due to the laze hazard.
  • Stay away from any ocean plume since it can change direction without warning.
  • The U.S. Coast Guard is actively monitoring the ocean entry area and enforcing a 300-meter standoff zone. Only permitted tour boats are allowed in the area.
  • Health hazards of laze include lung, eye and skin irritation.
  • Be aware that the laze plume travels with the wind and can change direction without warning.
  • Tankers are providing drinking water in Vacationland & Kapoho.
  • For those evacuating, the Pahoa Community Center, Keaau Community Center, and Sure Foundation Church are open. Food will be provided and the shelters are pet-friendly.

A third shelter has opened. Sure Foundation, located on Pohaku Circle in Keaau, is now open.

  • People from Pahoa who have breathing concerns are relocating from the Pahoa Community Center shelter to the Sure Foundation shelter. The shelter will cater specifically to people with breathing issues, but everyone is welcome.

Due to the changing conditions, the following policies are in effect:

  • Take action to limit further exposure and be prepared to leave the area with little to no notice if necessary.
  • Visibility may decrease. First responders are asking everyone be safe on the roadways and slow down.
  • Ash fallout may cause poor driving conditions. Drive with extreme caution, or pull over and park.
  • Stay alert for warnings from Civil Defense officials.

Sulfur Dioxide (SO2) and Vog

Volcanic gas emissions remain elevated throughout the area downwind of the vents in lower Puna.

  • Severe conditions may exist such as choking and inability to breathe.
  • Sulfur Dioxide (SO2) gas from fissures are especially dangerous for elderly, children/babies and people with respiratory problems.

County, State, and Federal partners continue to monitor the situation. You will be informed of any conditions that affect your safety.

Monitor vog levels and forecasts: People on Hawaii Island outside the area of volcanic activity are also advised to monitor levels of vog at vog.ivhhn.org

The residents of Puna are going through a very difficult time. We ask for your help and understanding.
